重试HTTP帖子，直到它们在Android上成功

Answer 1

有几种选择可以做到这一点：

凌空抽射：

RequestQueue queue = Volley.newRequestQueue(ctx); // ctx is the context
StringRequest req = new StringRequest(Request.Method.GET, url,
    new Response.Listener<String>() {
        @Override
        public void onResponse(String data) {
            // We handle the response                           
        }
    },
    new Response.ErrorListener() {
        @Override
            // handle response
        }
    );
queue.add(req); 

OKHTTP：

OkHttpClient client = new OkHttpClient();
client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Request request, IOException e) {
        // Handle error
    }

    @Override
        public void onResponse(Response response) throws IOException {
        //handle response
    }
});
